It can further be observed that, in case the pump would stop, the splash lubrication could replace the lubrication under pressure the pockets 15 being in communication with the supply of oilcontained in the case through the medium of the ducts 15. Finally, as hereinbefore described, the lubrication of the worm 11 and of the pinion 10 is obtained by means of the flow of oil taking place through to said pockets, a duct formed in said jacket for introducing oil from a different source to said pocket, and another duct for leading the oil collected in said pocket to the interior of the jacket.
